It has 113-cc intake ports, 2.25-inch intake valves and 1.88-inch exhaust valves, a massive 1150cfm carb (yes, a carb), a solid-roller cam with 0.714 inches of lift, 12:1 compression, and it requires 110 octane fuel. Here’s GM’s succinct English translation of those stats:
It also favors a hydraulic roller camshaft instead of the original’s flat-tappet cam. It makes a few extra ponies over the old model, too: 480 horsepower and 490 lb-ft of torque will melt any tires this engine’s hooked up to.
It also takes more torque to get oversized wheels turning which saps overall output and drains the gas tank much faster than normal. Swapping to lower gears and increasing the number in your gear ratio may be enough to offset the difference. A notable exception here is diesels, which sometimes put out so much torque that the difference with larger wheels isn’t noticeable.
A Jeep is a good place to start when you want to get off the pavement and into some fun situations. However, if you’re looking to really tackle the wilderness, you need more than just a little more clearance. Use this list of Jeep mods to start planning your build to get in and out of some rough spots.
The Dodge Grand Caravan has been one of the top selling minivans since it was introduced for the 1984 model year. The Grand Caravan is so popular that more than 11 million units have been sold globally, with several million units having been sold in North America alone. With so many new units sold, you would assume that the Dodge Grand Caravan would be on a list of great used minivans. You would be wrong.
We do have to point out that the Sedona offers less cargo space than several of the used minivans on the list and does not offer removable second-row seating on any trim level. Those shortcomings are overcome in our minds by the generous warranty, low sticker price, and long-term durability of the Kia Sedona.
It’s not that we’re going in cost order here, the LS9 crate engine ranks near the top because of its insane rarity. According to GM they aren’t building any new ones, they’re just selling the leftovers from the 2009-2013 Corvette ZR1. You know, the first Corvette to ever exceed 200 miles per hour. The one that lapped the Nurburgring four seconds faster than a Nissan GT-R way back in 2009. Nevermind that this happened nearly a decade ago the 6.2-liter LS9 is still insane today.
This is one of the best old Ford trucks as far as we are concerned, but they can be hard to come by. Restored versions tend to be pricey but it’s a great choice if you can get ahold of one.
A big block has higher weight and density in the block, as well as larger valve bores, a longer stroke, and a generally larger exterior size. A big block can have the same displacement as a small block, but only the most extreme small blocks encroach on this territory.
Remember those COPO Camaros of the 1960s we talked about earlier? The baddest of the bad, the stuff of bedroom posters and “I swear I saw one” stories, the kind of car the uber-rich still build replicas of today? Well in 2011 Chevrolet modified a modern Camaro in a COPO sort of way and took it to SEMA, and the response was overwhelming. So they built it for real. And at its heart, you could have this: a 5.7-liter supercharged 350 crate engine dubbed the COPO 350.
This is why you should be equipped with recovery gear. Tow and/or ratchet straps can come in handy in countless ways and you should always have a full size spare. These also stow away easily so they don’t take up much space or make a mess of your interior. When it comes to changing that spare, you may also have to look at a jack that can overcome your increased ride height.
With bigger tires and heavier rims on your list of Jeep mods, the stock gear ratio may not be enough to get you where you want to go. This is where changing the gear ratio comes in handy and reduces unreasonable stress on the engine. If the wheels are too tall for the stock gear ratio, there will be a noticeable power drop off from its stock build.
Like the old COPOs of the 60s, the 2011-14 models adhered to strict NHRA guidelines. That meant super-small production numbers and a price payable only by professional race teams. It also meant the car’s engine could only make 530 horsepower. But much like the Japanese engine restrictions of the 1990s, that figure seems to have been framed in air quotes. In 2016 a (not extensively) modified 2014 COPO Camaro ran an 8.323-second quarter mile at 165.80 miles per hour. Doing the math, that car was making closer to 1200 horsepower. 1200.
